Product Overview
The Bently Nevada 3500/42M 176449 - 02 is the core 4-channel monitoring module of the Bently 3500 machinery protection system. Originally manufactured in the USA, it is specifically designed to adapt to proximity probes and seismic sensor signals. It can acquire and process various operating parameters of rotating machinery in real time. By comparing the processed signals with user-preset alarm thresholds, it promptly triggers alarms or equipment protection actions, while simultaneously synchronizing critical equipment operating information with maintenance personnel. This prevents unplanned downtime or serious damage to equipment, making it a core component for health management of critical rotating equipment in industrial fields.
Core Technical Parameters
Electrical Parameters: Sensor power supply is -24VDC; input voltage supports 24VDC±10%. The device offers multiple sensitivity settings for various monitoring parameters. For radial vibration, axial displacement, and eccentricity, the sensitivity is selectable at 3.94 mV/μm or 7.87 mV/μm; for differential dilation, it's 0.394 mV/μm or 0.787 mV/μm; for REBAM, it's 40 mV/μm or 80 mV/μm; dual acceleration sensitivity reaches 10 mV/(m/s²), while dual velocity sensitivity is available in various specifications such as 20 mV/(mm/s) pk. The module resolution reaches 0.1 μm, with a measurement accuracy of ±0.1% and a sampling rate of 1 kHz, enabling precise capture of minute parameter changes.
Measurement range: Vibration-related measurements cover a multi-dimensional range, with acceleration measuring from 0.1g to 10g, and extending to ±20g in some scenarios; vibration velocity measurement range is ±25 mm/s peak value, and displacement measurement range is 0-200 mm. With a frequency response range of 5Hz to 10kHz, it can capture vibration signals across different frequency ranges, adapting to the operating characteristics of various rotating equipment.
Physical and Environmental Parameters: This module weighs approximately 0.4kg. Dimensions may vary depending on the source; one precise dimension is 24cm × 2.4cm × 10cm, while others are labeled 220mm × 170mm × 55mm, etc. The specific dimensions should be based on the actual 3500 system rack it is compatible with. It is rack-mounted in a 19-inch 3500 system and has an IP67 protection rating, resisting dust and moisture in industrial environments. The operating temperature range is -40°C to +85°C, and the storage temperature range is also -40°C to +85°C, enabling it to withstand harsh industrial conditions such as high and low temperatures.
Features
Multi-channel Independent Adaptation: The module's four monitoring channels are isolated from each other and can be individually programmed via the 3500 rack configuration software. They can receive signals from various sensors such as displacement, velocity, and acceleration, and can also specifically monitor multiple key parameters such as radial vibration, thrust position, eccentricity, and differential expansion. The channel isolation design also avoids signal cross-interference, ensuring data accuracy.
Intelligent Alarm and Self-Diagnosis: Supports customizable alarm thresholds and two-level relay output functions (warning and danger). When monitored parameters exceed the threshold, an alarm or equipment shutdown protection action can be quickly triggered. It also has over-range protection and fault self-diagnosis capabilities, enabling real-time monitoring of its own operating status, facilitating timely troubleshooting by maintenance personnel.
Strong Compatibility and Flexible Communication: Data transmission can be achieved through the 3500 system backplane, allowing seamless integration with other modules in the 3500 series to form a complete equipment monitoring system. Furthermore, it supports multiple communication interfaces such as RS485, Ethernet, and CAN bus, and some are compatible with the Modbus communication protocol, allowing for convenient access to industrial control systems and achieving efficient data transmission and sharing.
Modular and easy to maintain: The modular structure design not only facilitates installation and disassembly on the 3500 system rack, but also allows for flexible expansion according to the monitoring needs of different industrial scenarios. During later maintenance, modules can be repaired or replaced without a complete shutdown, reducing the impact of maintenance on production.
